GD fun!

Wally-o

Well, maybe this is a newbie question, but GD doesn't seem to be a newbie topic... anyways...

I'm having trouble with the TTF support for GD. Images are created/displayed fine, but when i try to use any function that requires me to link to a TTF font, it craps out.

Here is my code (copied almost directly from one of the articles on GD at this site):

<?
Header("Content-type: image/png");
if(!isset($s)) $s=11;
$text = "Wally";
$font = "Arlrdbd.ttf";
$size = imagettfbbox($s,0,$font,$text);
$dx = abs($size[2]-$size[0]);
$dy = abs($size[5]-$size[3]);
$xpad=9;
$ypad=9;
$im = imagecreate($dx+$xpad,$dy+$ypad);
$blue = ImageColorAllocate($im, 0x2c,0x6D,0xAF);
$black = ImageColorAllocate($im, 0,0,0);
$white = ImageColorAllocate($im, 255,255,255);
ImageRectangle($im,0,0,$dx+$xpad-1,$dy+$ypad-1,$black);
ImageRectangle($im,0,0,$dx+$xpad,$dy+$ypad,$white);
ImageTTFText($im, $s, 0, (int)($xpad/2)+1, $dy+(int)($ypad/2), $black, $font, $text);
ImageTTFText($im, $s, 0, (int)($xpad/2), $dy+(int)($ypad/2)-1, $white, $font, $text);
ImagePNG($im);
ImageDestroy($im);
?>

it gives me errors (@vx; whats this??) on lines 6, 17, and 18, exactly where I'm using $text, the variable that links to my TTF file (I'm sure that the filename is correct, btw). If I comment out thes lines, no problems occur.

So, can anyone help me pinpoint the problem? I'm using GD "2.0 or higher" as reported by PHPinfo(), freetype support is enabled, and I have freetype linkage "with freetype", whatever that means.

Also, another question on an (almost) unrelated topic, Where can I get GD with GIF support. The only one that I found was at http://php.weblogs.com/php_gd, but for some reason it doesnt work (the pages take forever to load); I think that its because it was compiled for PHP v. 4.0.3, and I have 4.0.1 ... hmm.

Well, any help would be appreciated. Thanks!

try to give it an absolute path to the font file.

in case you copy all fonts to the directory 'fontdirectory' it would be:

$path2fonts  = $DOCUMENT_ROOT."/fontdirectory";
$size = imagettfbbox($s, 0, $path2fonts."/".$font, $text);
/// and so on...
ImageTTFText($im, $s, 0, (int)($xpad/2)+1, $dy+(int)($ypad/2), $black, $path2fonts."/".$font, $text); 
ImageTTFText($im, $s, 0, (int)($xpad/2), $dy+(int)($ypad/2)-1, $white, $path2fonts."/".$font, $text);

what's your PHPinfo say about GD:

<?
phpinfo();
?>

Look for GD, I used that font this morning, works great for me. Is the font you are looking for stored in the same directory as the script you are accessing it from?

hmm.. using the full path to the font didn't fix the problem: I still get the same error 🙁

ucbones: this is what phpinfo() says about my GD:

GD Support - enabled
GD Version - 2.0 or higher
FreeType Support - enabled
FreeType Linkage - with freetype
JPG Support - enabled
PNG Support - enabled
WBMP Support - enabled

is this what it should say??

BTW, im using win. 98, with phptriad (php4.1.1, not 4.0.1, as i said earlier)
thanks for your help, to both of you.. 🙂

i think crosbystillsnas might have the answer.

the following (i changed $font to absolute path) and it works for me, though i'm running xp pro, php 4.3.2 w/ gd2 and apache.

<?
Header("Content-type: image/png"); 
if(!isset($s)) $s=11; 
$text = "Wally"; 
$font = "c:\\windows\\fonts\\Arlrdbd.ttf"; 
$size = imagettfbbox($s,0,$font,$text); 
$dx = abs($size[2]-$size[0]); 
$dy = abs($size[5]-$size[3]); 
$xpad=9; 
$ypad=9; 
$im = imagecreate($dx+$xpad,$dy+$ypad); 
$blue = ImageColorAllocate($im, 0x2c,0x6D,0xAF); 
$black = ImageColorAllocate($im, 0,0,0); 
$white = ImageColorAllocate($im, 255,255,255); 
ImageRectangle($im,0,0,$dx+$xpad-1,$dy+$ypad-1,$black); 
 ImageRectangle($im,0,0,$dx+$xpad,$dy+$ypad,$white)
; 
ImageTTFText($im, $s, 0, (int)($xpad/2)+1, $dy+(int)($ypad/2), $black, $font, $text); 
ImageTTFText($im, $s, 0, (int)($xpad/2), $dy+(int)($ypad/2)-1, $white, $font, $text); 
ImagePNG($im); 
ImageDestroy($im); 
?>

hmm.. i copied your script exactly, and i still get the same error..
im really confused ;(

crosbystillsnas

whats the error message like?
only '@vx;'

Wally-o

The error I'm getting is:
 
Warning: @vx in c:\apache\htdocs\graphics\button.php on line 6 
 
Warning: @vx in c:\apache\htdocs\graphics\button.php on line 17 
 
Warning: @vx in c:\apache\htdocs\graphics\button.php on line 18 
‰PNG

IHDR ÿîƒ PLTE,m¯ÿÿÿ¨ˆIDATxœcXµª¡Á'žê¡_?¹ÁoäIEND®B`‚

with all of the html present, not like a normal error that shows the "Warning" in bold and the rest normal.. like, well, a normal error. Plus I get a bunch of junk at the end, which i take to be the browser's (IE) feeble attempt to show a PNG.

The path that I am using now is: $font = "c:\windows\fonts\Arlrdbd.ttf"; However, the error was the same with just the font name ($font = "Arlrdbd.ttf"😉 when I had the font in the same folder as the script.

Thanks for all your help,

<desperation>try a different font!!</desperation>

Wally-o

Yep, i get the same error with other fonts, too...

Wally-o

well, i got tired and pissed off, so i reinstalled phptriad, and, to my amazement, it worked!
I still, however, dont know what went wrong, but i could care less 🙂

Thanks for all your help!
